Abstract

PURPOSE: To extract inflammable cracked gas dissolved in insulating oil, in particular, and analyze the extracted gas, in a simple apparatus and by simple procedure, by circulating the extracted gas while bubbling the liquid contained in an extractor.
CONSTITUTION: A gas circulation pump 5 is operated, and the air contained in a gas extractor 11 is caused circulated to flow to a circulation port 7 by way of a circulation port 8 and a porous plate 6. Next, a fixed quantity of oil is injected from a sample lead-in part 9. The oil sample 3 is held on the plate 6, and is bubbled by the air. Upon lapse of a certain time, the pump 5 is stopped, and a valve 12 is opened, so that the extracted gas is analyzed by a gas detector 13 which utilizes the air as carrier gas to find the concentration of inflammable gas. The sample 3 dropped beneath the plate 6 is discharged from a sample discharge part 10.
